LD-PD’S LP-MIR-5.2C Mid-Wavelength Long Optic Path Cell special designed for Fourier transform infrared spectroscopy and QCL TDLAS Application. The detection light could be MIR incoherent light source(Wideband) or Narrowband QCL DFB Light source. In order to meet the requirements of high temperature and corrosion resistance, the main body and optical components are made of special metal materials which have been treated with anticorrosion. The cell working temperature can reach 200℃. It can work stably and reliably for a long time under the condition of hot and humid corrosive gas. For the main gases including S02, NOx, VOCs, NH₃, O₂, CO, CO₂, HF, HCL, H₂O, etc. We can have Accurate measurement and analysis. Our LP-MIR-5.2C Mid-Wavelength Long Optic Path Cell  has wide application prospects in many fields, such as monitoring of major air pollutants, monitoring of coal-fired flue gas emissions, monitoring of waste incineration emissions, monitoring of pollutants in chemical industrial parks and on-line industrial control etc.
